Phospholipid vs. Phosphoglyceride

Phospholipids, also known as phosphatides, are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group, and two hydrophobic "tails" derived from fatty acids, joined by a glycerol molecule. Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule.

(organic chemistry) a phosphatide combined with a small, basic molecule (such as choline or ethanolamine); a phospholipid

a lipid containing a phosphate group in its molecule, e.g. phosphatidylcholine.

Any of various phosphorus-containing lipids, such as lecithin and cephalin, that are composed mainly of fatty acids, a phosphate group, and a simple organic molecule. Also called phosphatide.

(organic compound) Any lipid, such as lecithin or cephalin, consisting of a diglyceride combined with a phosphate group and a simple organic molecule such as choline or ethanolamine; they are important constituents of biological membranes.

any of various compounds composed of fatty acids and phosphoric acid and a nitrogenous base; an important constituent of membranes
